'Extremely disturbing': Gabi Grecko responds to claims her ex Geoffrey Edelsten has taken out an AVO

Geoffrey Edelsten's third ex-wife Gabi Grecko has denied his claims that she is planning to return to Australia, after he claimed he had taken out an AVO against her and said he wanted her "arrested" if she did come back.

The 27-year-old American model took to Instagram to rubbish her 73-year-old ex-husband's claims, after he told 9NEWS she was planning to visit but would be "stupid if she did".

"I am not coming to Australia to see this person," Ms Grecko wrote in a post.

"Please stop the harassment and let me live a free and peaceful life, this is extremely disturbing and controlling.

"I just want to pursue my interests and they have nothing to do (sic) my an old marital union that did not work.

"It's sad when someone tries to control with fancy, dishonest manipulation but I believe the Australian authorities will see past this immature ploy."

Dr Edelsten was this morning seen walking out of a police station on Melbourne's Spencer Street.
